* punycode_strerror:
* @rc: an #Punycode_status return code.
*
* Convert a return code integer to a text string. This string can be
* used to output a diagnostic message to the user.
*
* PUNYCODE_SUCCESS: Successful operation. This value is guaranteed
* to always be zero, the remaining ones are only guaranteed to hold
* non-zero values, for logical comparison purposes.
* PUNYCODE_BAD_INPUT: Input is invalid.
* PUNYCODE_BIG_OUTPUT: Output would exceed the space provided.
* PUNYCODE_OVERFLOW: Input needs wider integers to process.
*
* Return value: Returns a pointer to a statically allocated string
* containing a description of the error with the return code @rc.
